Confusion different types of primers

So let's see, there are small rifle, large rifle, small pistol and large pistol primers, and each of these come in a magnum version as well.

Two questions:
Are there any other types?
Are any of them interchangeable? I notice that a small rifle primer and a small pistol primer are pretty much the same size. What's the difference?

Your confusion will be cleared up by strictly following reloading data from reliable sources. Most reloading manuals have tables of showing equivalent primers from various vendors.

Do no deviate from published data, till you are willing to rework the load up starting over from scratch.

Small measure .175"
Large measure .210" but large rifle primers are thicker

Each company has a proprietary priming compound. So there are differences, hence they are not interchangeable.... Again you need to Buy and Read The ABC's of Reloading. This will help you build a foundation on reloading. Your next step is to assemble a library of good manuals, ie Sierra, Lyman, Hornady, and then download all the powder mfg data so you can cross reference data!
